frederick..........you know how when you startle a crayfish they scoot away from you in that jerky scoot , that motion is best imitated with the buggers and those type flies , but when they get to the end of the scoot , they kind of hang there a few seconds , thats the time for the clouser , you just have to figure out what stage of the scoot they are lookin for , but you will , that's what makes it so much FUN.
